Abstract: An electrochromic assembly (10,110,130,150) for rearview mirrors, windows, vehicle sunroofs, information displays, office partitions and other structures comprises a pair of optically aligned, electrochromic devices defined by at least one transparent sheet (12,14,16,112,114), first and second layers of electrochromic material (M1,M2) adjacent opposing surfaces of the sheets, the transmittance of the layers being variable when an electrical field is applied, and electrical conductors (18,20,22,24)) for applying such an electrical field. Electrical energy is switched alternately from one device to the other for short periods of time while the remaining device is alternately bleached. A reflective coating (42) may be included to allow operation as a dimming mirror. Anti-reflection (46) and index of refraction matching coatings may be included to enhance transmission. Electrical energy may also be applied to both devices simultaneously to provide a deeper level of coloration than is possible from either device alone.

Abstract: A microcomputer comprises a central processing unit, a watchdog timer generating a watchdog timer processing request when an overflow occurs in the watchdog timer, and an interrupt controller processing as a non-maskable interrupt the watchdog timer processing request generated by the watch timer. The central processing unit generates a preset signal to the watchdog timer at a beginning of execution of another interrupt processing by the central processing unit, so as to preset the watchdog timer. The interrupt controller responds to the preset signal for cancelling the watchdog timer processing request generated by the watchdog timer in a period of time of retaining the watchdog timer processing request by the interrupt controller.

Abstract: The subject of the innovation is a device by means of which containers in which water accumulates in an undesirable manner are automatically drained. An outer housing (2, 3) which can be inserted into the container bottom is subdivided by a web (8a) into two chambers, of which one is connected to the interior of the container and the other to the environment of the container. The web encloses an aperture (20) which connects the two chambers to each other when a valve member (14) has moved away from a seat (8b) surrounding the aperture. When the valve member rests on the seat, the chambers are separated from each other and the interior space of the container is not connected to the environment of the container. The movement of the valve member is controlled by the water level in the chamber which is connected to the interior space of the container.

Abstract: A compact printer capable using any of a plurality of printing tracks or colors of an ink ribbon is disclosed in which line drive means for driving a print head (1) are also used for operating ribbon shift means in order to select a desired printing track or color. Preferably, the stroke of a reciprocating movement of the print head is divided into a printing region within which printing on a recording paper (7) is performed, and two non-printing end regions. The ribbon shift means is operated in response to the line drive means moving the print head into a non-printing end region. Moving the print head into one end region causes a track setting mechanism to set a desired printing track, whereas moving the print head into the opposite end region causes a track resetting mechanism (50) to release the track setting by the track setting mechanism. A cam member having a stepped cam face provided on a pivotally supported setting lever which is operated by engagement with the print head is used as the track setting mechanism. Also disclosed is a control method for controlling this printer such as to allow multi-color printing.

Abstract: Ink jet print quality is improved and higher pen speed permitted by a bidirectional printing protocol. According to the new protocol, each individual character to be printed is first partitioned into a leading portion and a trailing portion. The trailing portion includes all trailing edge bits. Only the leading portion is printed on a forward pass of the ink jet pen. The trailing portion is printed on a reverse pass of the pen, so that trailing edge ink drops are instead printed as leading edge ink drops. As a result, satellite ink drops are directed toward the center of the character, where they are covered by primary ink drops, thereby minimizing character edge roughness associated with exposed satellite ink drops.

Abstract: A swash plate tiltably supported on a drive shaft is controlled by adjusting the pressure in a crank chamber. When an electromagnetic valve is de-excited, the high-pressure refrigerant gas in a discharge chamber is supplied to the crank chamber so that the inclination angle of the swash plate is shifted to its minimum inclination from its maximum inclination. An open/close mechanism located in a suction passage opens or closes the suction passage in accordance with the differential pressure between the pressure in the external refrigeration circuit located upstream the open/close mechanism and the pressure in a suction chamber. When the inclination angle of the swash plate is minimized, the open/close mechanism closes the suction passage. It is therefore possible to prevent frosting while also suppressing rapid changes in load torque.
